Abstract
Rechargeable and non-rechargeable collared containers for airtight packaging of oxygen and/or moisture sensitive liquid formulas, such as retinol and retinol-containing compositions, for preservation of these substances. Collared containers include inner container collars that are able to be coupled with inner containers that store cosmetic substances therein. The inner container collars are securable to outer containers, and dispenser collars are securable to the outer containers for airtight storage and delivery of cosmetic substances within and from the inner containers and prevention of exposure of the cosmetic substances to air outside the outer containers. Airless pump dispensers can be used for creation of vacuums and maintenance of air-tight seals, and inner containers can be flexible pouches, flexible blow mold bottles, or rigid containers containing pistons.
